tests: add commit hashes to log commands in rebase tests
Commit hashes are a useful way to ensure the content of commits made in the
tests are not changing, even if we don't query every aspect of every commit.
(And some properties, like extras, are rarely printed at all.)
Many of the rebase log -G calls didn't show hashes; by adding hashes to places
that weren't showing them we can help protect those tests from unwanted
changes.

Function to check that statprof ran
$ statprofran () {
> egrep 'Sample count:|No samples recorded' > /dev/null
> }
test --profile
$ hg st --profile 2>&1 | statprofran
Abreviated version
$ hg st --prof 2>&1 | statprofran
In alias
$ hg --config "alias.profst=status --profile" profst 2>&1 | statprofran

Profiling of HTTP requests works
$ $prof --config profiling.format=text --config profiling.output=../profile.log serve -d -p $HGPORT --pid-file ../hg.pid -A ../access.log
$ cat ../hg.pid >> $DAEMON_PIDS
$ hg -q clone -U http://localhost:$HGPORT ../clone
A single profile is logged because file logging doesn't append
$ grep CallCount ../profile.log | wc -l

Install an extension that can sleep and guarantee a profiler has time to run
$ cat >> sleepext.py << EOF
> import time
> from mercurial import registrar, commands
> cmdtable = {}
> command = registrar.command(cmdtable)
> @command(b'sleep', [], 'hg sleep')
> def sleep(ui, *args, **kwargs):
> time.sleep(0.1)
> EOF
$ cat >> $HGRCPATH << EOF

> sleep = `pwd`/sleepext.py

statistical profiler works
$ hg --profile sleep 2>../out
$ cat ../out | statprofran
Various statprof formatters work
$ hg --profile --config profiling.statformat=byline sleep 2>../out
$ head -n 1 ../out
% cumulative self
$ cat ../out | statprofran
$ hg --profile --config profiling.statformat=bymethod sleep 2>../out
$ head -n 1 ../out
% cumulative self
$ cat ../out | statprofran
$ hg --profile --config profiling.statformat=hotpath sleep 2>../out
$ cat ../out | statprofran
$ hg --profile --config profiling.statformat=json sleep 2>../out
$ cat ../out
